Chain saw case having chain saw scabbard with adjustable length

ABSTRACT

A chain saw case has an adjustable scabbard that telescopes to allow for different lengths of chain bar. The scabbard also has an opening along one side to allow visibility of the side of the chain saw bar and any markings, including branding, on the chain saw bar. The chain saw case is designed to be fabricated using injection-molding techniques. Because the scabbard collapses, and the injection molded case offers ample space not afforded in all existing blow molded chain saw cases, the scabbard can be placed inside the case during shipment reducing shipping cost and space required while in distribution.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a plastic case including a scabbard for housing a chain saw, and more particularly to a plastic case having a scabbard that is adjustable to house chain bars having different lengths.

2. Discussion of the Related Art

Currently, a variety of plastic cases are used to hold chain saws. Such known cases share the characteristic that the chain bar is held within a plastic scabbard that extends from the body of the case.

Chain Bars having different lengths may be placed on the chain saw. Thus, a single chain saw may accommodate chain saw bars of different length. Typically, chain saw bars are selected from the lengths of 16, 18, and 20 inches. The result is that known cases have excessively long scabbards that can accommodate the longest possible chain bar length. Otherwise, a different size scabbard may be required for the same chain saw when different length chain bars are attached to the chain saw.

In addition, most conventional chain saw bars 200, as shown in FIG. 1, include merchandising, branding or other markings thereon. Known chain saw cases and scabbards that protectively cover the chain bar also completely enclose the chain bar, thus covering any markings, merchandising or branding on the side of the chain saw bar.

Currently, no chain saw case exists that allows for housing different lengths of chain bars. Also, no chain saw case exists that allows for visibility of markings, merchandising or branding on the chain saw bar when the chain saw is held in the case.

Moreover, current chain saw cases have a scabbard that extends from the case, making stacking and storage difficult.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Reference will now be made in detail to the preferred embodiment of the present invention, example of which is illustrated in the accompanying drawings.

As shown in FIGS. 2A and 2B, a case 4 for housing a chain saw 8 includes a main compartment 12 formed of a base 16, and a cover 24. The case further includes a scabbard 32 for housing the chain bar of a chain saw 8.

As shown in FIG. 2B, a conventional chain saw 8 includes a main chain saw portion 40 and a chain saw bar 42 (partially shown). The chain bar portion is shown in more detail in FIG. 2.

The scabbard 32 is hollow to hold the chain bar 42 therein. The scabbard 32 includes a first scabbard portion 50 and a second scabbard portion 54, as shown in FIG. 3. The first scabbard portion 50 has a proximal end 58 and a distal end 60.

The proximal end 58 of the first scabbard portion 50 engages a slot 20 in the side wall 62 of the main compartment 12 of the case 4. The first scabbard portion 50 can also be removed from the slot 20, as shown in FIGS. 4A and 4B. For example, the proximal end 58 of the first scabbard portion 50 slides into and nests in the slot 20, which may have any shape, for example a “U” shape. The proximal end 58 of the first scabbard portion 50 thus engages the side wall 62 so that the chain saw bar 42 of a chain saw 8 placed in the main compartment 12 of the case 4 can be housed in the scabbard 32, while the main body 42 of the chain saw 8 is held in the main compartment 12. The proximal end 58 of the first scabbard portion 50 can be unfitted from the slot 20, and thus the scabbard 32 can be entirely removed from the case 4. The scabbard 32 can then be placed inside the main compartment 12 for shipping or shipped separately from the case 4. Thus, the shipping and storage of the case is more convenient and efficient.

The second scabbard portion 54 has a proximal end 102 and a distal end 104.

The scabbard 32 has a cross section that is substantially in the shape of an elongated “C”. In the scabbard 32 shown in FIG. 3, the elongated “C” shape of the scabbard 32 is an inverted “C”. The elongated “C” shape allows for an open portion on one side of the cross section of the scabbard 32. The first scabbard portion 50 has a longitudinal wall 66, a top wall 70, a bottom wall 74, and longitudinal wall portions 78. A distance d1 separates the longitudinal wall portions. The top wall 70 and the bottom wall 74 are curved and opposite to one another. The longitudinal wall 66 is substantially parallel to the longitudinal wall portions 78. Along the top wall 70 of the first scabbard portion 50 are a plurality of notches 80. Alternatively, the notches 80 may be along the bottom wall 74 of the first scabbard portion 50 or along both the bottom wall 74 and the top wall 70.

The second scabbard portion 54 has a longitudinal wall 86, a top wall 90, a bottom wall 94, and longitudinal wall portions 98. A distance d2 separates the longitudinal wall portions 98. The top wall 90 and the bottom wall 94 are curved and opposite to one another. The longitudinal wall 86 is substantially parallel to the longitudinal wall portions 98. The proximal end 102 of the second scabbard portion 54 includes a resilient ridge portion or protrusion (not shown). Shape and dimension of the ridge portion are complementary to each notch 80 such that the ridge portion fits within each notch 80.

In another embodiment, the notches 80 are included on second scabbard portion 54, and the resilient ridge or protrusion is on the first scabbard portion 50.

The second scabbard portion 54 slideably inserts into the first scabbard portion 50. The proximal end 102 of the second scabbard portion 54 inserts into the distal end 60 of the first scabbard portion 50 such that the second scabbard portion 54 slides within the first scabbard portion 50. The second scabbard portion 54 is free to slide within the first scabbard portion 50 until the ridge of the second scabbard portion 54 engages one of the plurality of notches 80.

When the ridge engages a first of a plurality of notches 80 a, the scabbard 32 has a first predetermined length; when the ridge engages a second of the plurality of notches 80 b, the scabbard 32 has a second predetermined length; when the ridge engages a third of the plurality of notches 80 c, the scabbard 32 has a third predetermined length. In a preferred embodiment, the first, second and third predetermined lengths are designed to hold chain saw bars having 20, 18, and 16 inches, respectively. Accordingly, one scabbard, and one chain saw case, accommodates 16 inch, 18 inch & 20 inch chain bars. Of course, other lengths of chain saw bar that can be accommodated is not limited to the disclosed lengths. The length of each scabbard portion, the placement of the notches, and the overall lengths of the scabbard can be designed to accommodate any desired length of chain saw bar.

The resilient ridge is deformable and thus can be released from the notch 80. Thus, the second scabbard portion 54 is free to slide within the first scabbard portion, and the resilient ridge is available to engage another of the plurality of notches 80. Therefore, the length of the scabbard 32 can be changed. Also, when no notch is engaged, the scabbard 32 can be collapsed by sliding the second scabbard portion 54 into the first scabbard portion 50. For shipping or storage, the scabbard 32 can be removed from the slot 20 in the side wall 62, collapsed, and placed inside the main compartment 12 of the case 4. Because the scabbard 32 collapses, the scabbard can be placed inside the case 4 during shipment, thus reducing shipping cost and space required while in distribution.

The distances d1 and d2 between the longitudinal wall portions 78 and 98, respectively, form a longitudinal opening 108 along one side of the scabbard 32. The opening 108 allows a portion of a chain saw bar 42 held in the scabbard 32 to be seen when the cover 24 is fitted onto the base 16 to hold a chain saw 8 within the chain saw case 4. Such visibility of the chain bar 42 allows for merchandising or branding information on the chain bar 42 to be seen. This allows for the chain saw 8 not only to be merchandised while in the retail store, but serves as a walking advertisement that builds brand image for the manufacturer while the consumer has the chain saw 8 safely inside his case. The scabbard 32 is designed to have an opening on one side only.

Preferably, the chain saw case 4 is manufactured using the injection molding process to achieve the unique features.

It will be apparent to those skilled in the art that various modifications and variation can be made in the chain saw case of the present invention without departing from the spirit or scope of the invention.
